In a series RC circuit, how does the total impedance (Z) relate to resistance (R) and reactance (Xc)?
Z = R + Xc
Z = R - Xc
Z = R*Xc
Z = R/Xc
Questions & Step-by-Step Solutions
In a series RC circuit, how does the total impedance (Z) relate to resistance (R) and reactance (Xc)?
Step 1: Understand that an RC circuit has two main components: a resistor (R) and a capacitor.
Step 2: Recognize that resistance (R) is the opposition to current flow in the circuit.
Step 3: Learn that reactance (Xc) is the opposition to current flow caused by the capacitor.
Step 4: Know that in a series RC circuit, the total impedance (Z) combines both resistance and reactance.
Step 5: The formula for total impedance in a series RC circuit is Z = R + Xc.
Step 6: Remember that Xc is specifically the capacitive reactance, which can be calculated using the formula Xc = 1/(2πfC), where f is frequency and C is capacitance.
