How much current is in a circult that includes a 9.0-volt battery and a bulb with a resistance of 4.0 ohms?
A.
0.44 amps
B.
36 amps
C. 2.3 amps
D. 13 amps

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 :

I is electric current

or

I = 2.3 A

So, the current in the circuit is 2.3 A.

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
