In the following diagram, the voltage is 1.5 volts and the resistance is 7.5 ohms. Use Ohm's law to determine the current in the circuit.
Answer: The current flowing through the circuit is 0.2 Amperes.
Explanation:
Ohm's Law is defined as the law which determines the relationship between current and potential difference across a resistor.
Mathematically,
\(V=IR\)
where,
V = Potential difference across the resistor = 1.5 V
I = Current flowing through the circuit = ? A
R = Resistor in the circuit = \(7.5\Omega\)
Putting values in above equation, we get:
\(1.5=I\times 7.5\\\\I=0.2A\)
Hence, the current flowing through the circuit is 0.2 Amperes.
