Question

a circuit is supplied with 30 volts and the total circuit resistance is 3 ohms what the current through the circuit flowing

Answer 1

10 amps

Explanation:

Ohm's law states

I =
`(V)/(R)`

I is the current, V the voltage and R the resistance, thus

I =
`(30)/(3)` = 10

Answer 2

The current is 10 amps

Explanation:

This problem bothers Ohms law

Which states that the the current passing through a wire is directly proportional to the potential difference between the ends provided the temperature of the wire remains constant.

V= IR

Where I =the current in amp

V= voltage in volts

R= resistance in Ohms

Given that v= 30volts

R= 3 Ohms

Substituting our data into the equation we have

30= I*3

I=30/3

I= 10 amps
