Question

A resistance of 30Ω is placed in a circuit with a 90 volt battery. What current flows in the circuit?​

Answer 1

Answer:

v= R×I

I = V/R

I = 90/30

I = 3 amp

Answer 2

Answer:

3A of current flows in the circuit.

Explanation:

We will solve this question through Ohms law. Which is given as,

$V=IR$       (1)

Where,

V=voltage across the battery

I=current flowing through the resistor

R=resistance of the resistor

From the question we have,

Resistance(R)=30Ω

The voltage of the battery(V)=90volt

By substituting the value of V and R in equation (1) we get;

$90=I\times 30$

$I=\frac{90}{30} =3A$

Hence, 3A of current flows in the circuit.
