Question

How many amps of current flow through a circuit that includes 27-v battery and a bulb with a resistance of 3 ohms?​

Answer 1

Answer:

9 amperes of current flows through the circuit.

Answer 2

Answer:

The circuit has a current flow of 9 amperes.

Explanation:

We will find the current flow through the circuit using Ohms law. Which is stated as,

"Ohm's law explains how electric current and potential difference are related. The voltage given to the majority of conductors determines how much current flows through them."i.e.

$\mathrm{V\propto I}$

$\mathrm{V=IR}$         (1)

Where,

V=potential difference across the circuit

I=current through the circuit

R=resistance of the circuit

From the question we have,

The potential of the battery(V)=27 volts

The resistance of the bulb(R)=3 ohms

By inserting the values of "V" and "R" in equation (1) we get;

$\mathrm{27=I\times 3}$

$\mathrm{I=\frac{27}{3} }$

$\mathrm{I=9\ A}$

So, 9 Amperes of current flows through the circuit.
