In a circuit under test a resistor, R, is connected in series with a capacitor, C. An a.c. current, i, flows through this RC combination, causing a voltage (Vr) of 6V to be developed across the resistor, and a voltage (Vc) of 8V to be developed across the capacitor. Assuming that: Vr is in-phase with i Vc lags Vr by 90 degrees draw a vector diagram for this arrangement and calculate the magnitude of the resultant voltage across the whole RC combination.
