What voltage required to force a current flow of 3 Amps if the resistance is 50 Ohms?

Question

Please help

Answer 1

The underlying formula that you want to use here is Ohm's Law, a fundamental principle in electrical engineering that defines the relationship between voltage, current, and resistance.

For this set of parameters that means taking

V = I x R = 3 x 50 = 150

meaning that the required voltage is 150 Volts (150 V)

Answer 2

V=IR

This is a simple plug-in and solve.

 

I= the current flow measured in amps

R= the resistance measured ohms

V= voltage (potential difference across the conductor measured in volts

 

V=3 x 50
