What is the current when the resistance is 5 ohms and the voltage is 10 volts? 10 ÷ 5 =
2 amps
.
What is the current through the 5 ohm resistor if the voltage across it is 10v?
Explanation: 10/5= 2 Current =
2 amperes
.
What is the value of resistance at V 10 volts and I 5a?
Use Ohm’s law to calculate the resistance. The resistance of a circuit with a voltage of 10 V and current of 5 A is
2 ohms
.
How do you find current with voltage and resistance?
From this, we conclude that;
Current equals Voltage divided by Resistance
(I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).
What is the current passing through the 5.0 ohm resistor?
The current through the 5-ohm resistor is
2.4 amperes
.
What is the voltage when the resistance is 6 ohms and the current is 8 amps?
8= E/6 voltage=
8 x6 48 volts
.
What is value of current in 5 ohm resistance?
Thus, current flowing in the 5ohm resistor is
2A
.
How many ohms does a 12 volt battery have?
The resistance “seen” by the 12-Volt battery is
500 ohms
. The total resistance is the sum of the resistors R1 and R2. Each resistor will drop a calculable amount of voltage. This voltage is given by Ohm’s Law.
What happens when voltage is increased?
The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the
voltage will cause the current to increase
, while increasing the resistance will cause the current to decrease.
How do I calculate resistance?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law:
R = V / I
. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance R
T
= 9 volts / 3 amps = 3 Ω.
What is the relation between resistance and current?
Ohm’s law defines the relationship between the voltage, current, and resistance in an electric circuit:
i = v/r
. The current is directly proportional to the voltage and inversely proportional to the resistance.
Is voltage directly proportional to resistance?
Ohm’s law Equation tells us that the current in a circuit can be determined if the values of resistance and voltages are known. … Therefore,
voltage is not proportional to resistance
.
Does resistance affect voltage?
Ohm’s law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and
inversely proportional to the resistance (R)
. … Similarly, increasing the resistance of the circuit will lower the current flow if the voltage is not changed.
What is the current through the 2.0 ohm resistor?
Answer: The current through 2 ohm resistor is
2.1 A
. Hence, the current through 2 ohm resistor is 2.1 A.
What is the current through the 20 ohm?
Explanation: I=V/R. Since in parallel circuit, voltage is same across all resistors. Hence across the 20 ohm resistor, V=200V so I=200/20=10A. … Current through 20 ohm equals 200 divided by 20 equals to
10 amp
.
What is the current through the 30 ohm resistor?
1 Expert Answer
So the current in the 30 Ω resistor is
2.00 amps
.
