What is the Thevenin equivalent voltage across a load resistor if the circuit has a 15V source and two resistors (5Ω and 10Ω) in series?
Step 1: Identify the components in the circuit. We have a voltage source of 15V and two resistors: R1 = 5Ω and R2 = 10Ω in series.
Step 2: Understand that we want to find the Thevenin equivalent voltage (Vth) across a load resistor (Rload). We will assume Rload = 10Ω for this calculation.
Step 3: Calculate the total resistance in the series circuit. Rseries = R1 + R2 = 5Ω + 10Ω = 15Ω.
Step 4: Use the formula for Thevenin voltage: Vth = Vsource * (Rload / (Rseries + Rload)).
Step 5: Substitute the values into the formula: Vth = 15V * (10Ω / (15Ω)).
