Questions & Step-by-Step Solutions
If a circuit has a Thevenin equivalent of 15V and a load resistance of 5Ω, what is the load current?
Steps
Concepts
Step 1: Identify the Thevenin equivalent voltage, which is given as 15V.
Step 2: Identify the load resistance, which is given as 5Ω.
Step 3: Use Ohm's law formula, which is I = V / R, where I is the current, V is the voltage, and R is the resistance.
Step 4: Substitute the values into the formula: I = 15V / 5Ω.
Step 5: Calculate the current: I = 3A.
Thevenin's Theorem
– Thevenin's Theorem simplifies a complex circuit to a single voltage source and a series resistance.
Ohm's Law
– Ohm's Law relates voltage (V), current (I), and resistance (R) in a circuit, expressed as I = V/R.
