Question: If a circuit has a Thevenin equivalent of 5V and 10Ω, what is the current through a load resistor of 5Ω connected across the terminals?

Options:

Correct Answer: 0.5A

Solution:

Using Ohm\'s law, the current through the load can be calculated as I = Vth / (Rth + Rload) = 5V / (10Ω + 5Ω) = 5V / 15Ω = 0.33A.

If a circuit has a Thevenin equivalent of 5V and 10Ω, what is the current through a load resistor of 5Ω connected across the terminals?

Step 1: Identify the Thevenin equivalent voltage (Vth) which is given as 5V.
Step 2: Identify the Thevenin equivalent resistance (Rth) which is given as 10Ω.
Step 3: Identify the load resistor (Rload) which is given as 5Ω.
Step 4: Calculate the total resistance in the circuit by adding Rth and Rload: Rtotal = Rth + Rload = 10Ω + 5Ω.
Step 5: Perform the addition: Rtotal = 15Ω.
Step 6: Use Ohm's law to find the current (I) through the load resistor: I = Vth / Rtotal.
Step 7: Substitute the values: I = 5V / 15Ω.
Step 8: Perform the division: I = 0.33A.

Thevenin's Theorem – Thevenin's Theorem simplifies a complex circuit to a single voltage source and series resistance.
Ohm's Law – Ohm's Law relates voltage, current, and resistance in a circuit (V = IR).
Series Resistance – When resistors are in series, their total resistance is the sum of their individual resistances.
