Question

An object with a resistance of 28 Ω has 76 V applied to it. How much electric current is going through this object? Answer in units of amps.

Answer 1

Answer : The electric current of a circuit is, 2.8 A.

Explanation :

Using Ohm's law :

$V=I\times R$

Or,

$I=\frac{V}{R}$

where,

R = resistance of a circuit = 28 Ω

V = voltage of circuit = 76 volts = 76 V

I = current flowing in a circuit = ?

Now put all the given values in the above formula, we get :

$I=\frac{V}{R}$

$I=\frac{76V}{28\Omega }$

$I=2.8A$

Therefore, the electric current of a circuit is, 2.8 A
