Question

How much voltage is required to run 0.054 A of current through a 15-ohm resistor? Use ΔV=IR.

Options:
A. 0.810 V
B. 1.125 V
C. 0.004 V
D. 0.270 V

Answer 1

The correct answer is option A.The voltage required to run 0.054 A of current through a 15-ohm resistor is 0.810 V.

Step-by-step explanation:

According to Ohm's law, the voltage drop, V, across a resistor when a current flows through it is calculated using the equation V = IR, where I equals the current in amps (A) and R is the resistance in ohms (Ω). In this case, the current is 0.054 A and the resistance is 15 Ω, so we can use Ohm's law to calculate the voltage drop:

V = (0.054 A) * (15 Ω) = 0.81 V

To calculate the voltage required to run 0.054 A of current through a 15-ohm resistor, we can use Ohm's law, which is given by the formula ΔV = IR. Plugging in the given values, we get ΔV = 0.054 A × 15 Ω = 0.810 V.

Therefore, the voltage required to run 0.054 A of current through a 15-ohm resistor is 0.810 V.
