Questions & Step-by-Step Solutions
A circuit has a 15V battery and a 5Ω resistor. What is the voltage drop across the resistor? (2021)
Step 1: Identify the components in the circuit. We have a 15V battery and a 5Ω resistor.
Step 2: Understand that in a simple circuit with a battery and a resistor, the voltage drop across the resistor is equal to the voltage of the battery.
Step 3: Since the battery provides 15V, the voltage drop across the 5Ω resistor is also 15V.
Ohm's Law – The relationship between voltage, current, and resistance in an electrical circuit, typically expressed as V = IR.
Voltage Drop – The reduction in voltage across a component in a circuit, which can be calculated using Ohm's Law.
