If a 15 V battery is connected to a 300 ohm resistor, what is the current in the circuit?

0.05A

Explanation:

Data obtained from the question include:

V (Voltage) = 15V

R (Resistor) = 300 ohms

I (current) = ?

From Ohms law, V = IR. With this equation, we can obtain the current flowing in the circuit as follow:

V = IR

I = V/R

I = 15/300

I = 0.05A

The current flowing through the circuit is 0.05A
