Current flowing through 8 ohm resistor is 1 Ampere .
What is the current through the 8 Ω resistor?
8. (Test Bank 45) What is the current through the 8 Ω resistor? Just after the switch is thrown, the capacitors have no effect. The current is therefore calculated from 20 / 8.1 = 2.5 A .
How do you find the current in A resistor?
Current through each resistor can be found using Ohm’s law I=V/R , where the voltage is constant across each resistor.
What is the potential drop across the 8 ohm resistor?
The potential difference across 8 ohm resistance is 48 volt as shown in the figure.
What is the current in the 5 Ω resistor?
So total current across 5 ohm resistor is zero .
What is the current through the 10 resistor?
The maximum current that can be passed through the 10 ohm resistor is 5/9 A .
What is the potential difference across the 10 Ω resistor?
Hence the potential difference at the 10 Ω resistor is 1.3 V .
How do you calculate the power of a resistor?
Power can also be calculated using either P = IV or P=V2R P = V 2 R , where V is the voltage drop across the resistor (not the full voltage of the source).
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.
Do resistors in parallel have the same current?
The potential drop across each resistor in parallel is the same . Parallel resistors do not each get the total current; they divide it. The current entering a parallel combination of resistors is equal to the sum of the current through each resistor in parallel.
How do you find the potential difference across a resistor?
The unit of potential difference generated between two points is called the Volt and is generally defined as being the potential difference dropped across a fixed resistance of one ohm with a current of one ampere flowing through it. In other words, 1 Volt equals 1 Ampere times 1 Ohm, or commonly V = I*R.
How do you find potential difference?
Multiply the amount of the current by the amount of resistance in the circuit. The result of the multiplication will be the potential difference, measured in volts. This formula is known as Ohm’s Law, V = IR .
When a resistance of 2ohm is connected across the terminals of a cell the current is 0.5 amperes when the resistance is increased to 5 ohm the current is 0.25 amperes the internal resistance of the cell is?
When a resistance of 2ohm is connected across the terminals of a cell the current is 0.5amperes but when the resistance across the cell is 5 ohm and the current 0.25 the emf of a cell is: 1.5V .
At which position should an ammeter be placed?
Answer: To measure the total current, the ammeter must be placed at position 1 , as all the current in the circuit must pass through this wire, and ammeters are always connected in series.
What is the current through the 30 ohm resistor?
1 Expert Answer
So the current in the 30 Ω resistor is 2.00 amps .
What is the current through the 2.0 Ω resistor?
Answer: The current through 2 ohm resistor is 2.1 A . Hence, the current through 2 ohm resistor is 2.1 A.
