Question:

A circuit consists of a resistor with a resistance of 10 ohms, connected to a 12-volt battery. Determine the current flowing through the circuit according to Ohm's law.

Answer:

According to Ohm's law, the current flowing through a circuit can be calculated using the formula:

I = V / R

where I is the current (in amperes), V is the voltage (in volts), and R is the resistance (in ohms).

Given:
Resistance of the resistor (R) = 10 ohms
Battery voltage (V) = 12 volts

Substituting the values into the formula, we have:

I = 12 V / 10 Ω

Calculating the value:

I = 1.2 A

Therefore, the current flowing through the circuit is 1.2 amperes.
