How much current is in a circult that includes a 9.0-volt battery and a bulb with a resistance of 4.0 ohms?

SVETLANKA909090 [29]

Answer:

Current, I = 2.3 A

Explanation:

We have,

Voltage of the battery in a circuit is 9 volts

Resistance of the circuit is 4 ohms

It is required to find the current in a circuit. When the voltage and the resistance of the circuit is given then we can find the current in it is given by Ohm's law as :

$V=IR$

I is electric current

$I=\dfrac{V}{R}\\\\I=\dfrac{9}{4}\\\\I=2.25\ A$

I = 2.3 A

So, the current in the circuit is 2.3 A.
