2, the current coming from the voltage source flows through each resistor, so the current through each resistor is the same . The current through the circuit depends on the voltage supplied by the voltage source and the resistance of the resistors.
Why do resistors have the same current?
Since there is only one path for the charges to flow through, the current is the same through each resistor . The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.
Which resistors in the circuit must always have the same current?
Answer Expert Verified The correct answer is D): resistors B and C. In the circuit in the figure, the resistors B and C are connected to the same points of the circuit (they are connected in parallel), therefore they have the same voltage, so they have the same energy per unit charge.
What remains the same in every part of the circuit for resistors in series?
In series combination of resistors the current is the same in every part of the circuit or the same current through each resistor and in parallel combination the voltage remains constant.
Is current the same in parallel?
A Parallel circuit has certain characteristics and basic rules: ... Voltage is the same across each component of the parallel circuit . The sum of the currents through each path is equal to the total current that flows from the source.
Is current the same in series or parallel?
In a parallel circuit , the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. ... In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.
Why the current in series connection is constant?
This is because there is continuity in the charge flowing . There is no accumulation of charge anywhere in the circuit. Hence, since, the electric charge flowing in the series circuit has to remain constant, the electric charge flowing per second in the circuit also has to remain constant.
Why is current same in series?
The amount of current in a series circuit is the same through any component in the circuit. This is because there is only one path for current flow in a series circuit .
Why is resistance less in parallel?
Resistors in parallel
In a parallel circuit, the net resistance decreases as more components are added , because there are more paths for the current to pass through. The two resistors have the same potential difference across them. The current through them will be different if they have different resistances.
Which is the most cost efficient connection?
Which is the most cost efficient connection? Explanation: The advantage of series-connections is that they share the supply voltage, hence cheap low voltage appliances may be used.
Is current constant in series?
In a series circuit the current is the same at any particular point on the circuit. ... The voltage in a series circuit, however, does not remain constant . 4. The voltage drops across each resistor.
What happens when resistors are connected in parallel?
When resistors are connected in parallel, more current flows from the source than would flow for any of them individually , so the total resistance is lower.
Why the current is not same in parallel circuit?
The current along the branch with the smallest resistance will be larger than the branch with higher resistance. The total current in the circuit must remain constant (so that charge is not created/lost). So the sum of the currents in the parallel branches will always be equal to the current before the junction.
Why current is divided in parallel?
When resistors are connected in parallel, more current flows from the source than would flow for any of them individually , so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst them.
Why current is different in parallel?
The current in a parallel circuit splits into different branches then combines again before it goes back into the supply . When the current splits, the current in each branch after the split adds up to the same as the current just before the split.
Does current stay the same in a series circuit?
UNDERSTANDING & CALCULATING SERIES CIRCUITS BASIC RULES
The same current flows through each part of a series circuit . The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops.
