The Calculation of Resistance in a Circuit with an EMF Source
What is the resistance of the lamp connected to an EMF source of 6.0V conducting a current of 2.0 amperes?
Given an EMF source of 6.0V connected to a purely resistive lamp with a current of 2.0 amperes, what is the resistance of the lamp?
Answer:
The resistance of the lamp connected to an EMF source of 6.0 V and conducting a current of 2.0 amperes is 3.0 ohms.
Explanation:
The problem involves finding the resistance of a lamp in a circuit where an EMF source of 6.0 V is connected, resulting in a current of 2.0 amperes flowing through the circuit. To determine the resistance of the lamp, we can utilize Ohm's Law.
Ohm's Law states that V = IR, where V is the voltage (EMF), I is the current, and R is the resistance. By substituting the given values into the formula, we get 6.0 V = 2.0 A * R. Solving for R, the resistance, we find R = 6.0V / 2.0A = 3.0 ohms.
Therefore, based on the principles of Ohm's Law and the provided parameters of the circuit, the resistance of the lamp would be 3.0 ohms.
