Question

if there is a resistance off 45 ohms and a current of 120amps , what is the voltage ? ​

Answer 1

Hello!

The answer is:  The voltage is 5400 Volts.

Why?

We can calculate the voltage using the Ohm's Law.

The Ohm'ws Law states that:

$V=I*R$

Where,

V, is the voltage in volts

I, is the current in amps

R, is the resistance in ohms

We are given:

$R=45ohms\\I=120Amps$

Now, calculating the voltage, we have:

$V=I*R=45ohms*120Amps=5400Volts$

Hence, the voltage is 5400 Volts.

We can also calculate the power using the following formula:

$P=V*I$

Where,

P, is the power in watts

V, is the voltage in volts

I, is the current in amps

So,

$P=5400Volts*120Amps=648000W$

Have a nice day!
