Goals
5. R–C series A.C. circuit
Figure 10
Classwork
• A resistor of 25Ω is connected in series with a capacitor of 45µF. Calculate
(a) the impedance, and (b) the current taken from a 240V, 50Hz supply.
Find also the phase angle between the supply voltage and the current.
Tutorial 3
• A capacitor C is connected in series with a 40 Ω resistor across a
supply of frequency 60Hz. A current of 3A flows and the circuit
impedance is 50 Ω. Calculate
• (a) the value of capacitance, C,
• (b) the supply voltage,
• (c) the phase angle between the supply voltage and current,
• (d) the p.d. across the resistor, and
• (e) the p.d. across the capacitor.
• Draw the phasor diagram.
6. R–L–C series A.C. circuit
• In an A.C. series circuit containing resistance R, inductance L and
capacitance C, the applied voltage V is the phasor sum of VR, VL and VC
(see Fig. 12). VL and VC are anti-phase, i.e. displaced by 180o,and there
are three phasor diagrams possible – each depending on the relative
values of VL and VC .
6. R–L–C series A.C. circuit (Contd.)
When XL=XC (Fig. 12(d)), the applied
voltage V and the current I are in
phase. This effect is called series
resonance (to be discussed)
Fig. 12
Classwork; A coil of resistance 5Ω and inductance 120mH in series with a 100µF
capacitor, is connected to a 300V, 50Hz supply. Calculate (a) the current flowing, (b)
the phase difference between the supply voltage and current, (c) the voltage across
the coil, and (d) the voltage across the capacitor.
Series-Connected Impedances
• For series-connected impedances the total
circuit impedance can be represented as a
single L–C–R circuit by combining all values
of resistance together, all values of
inductance together and all values of
capacitance together, (remembering that
for series connected capacitors
• For example, the circuit of Fig. 15(a)
showing three impedances has an
equivalent circuit of Fig. 15(b).

10. Power in A.C. circuits
• In Figs. 23(a)–(c), the value of power at any instant is given by the
product of the voltage and current at that instant, i.e. the
instantaneous power, p=vi, as shown by the broken lines.

Tutorial 6
A coil consists of a resistance of 100 Ω and an inductance of 200mH. If an alternating voltage, v,given
by v=200 sin500t volts is applied across the coil, calculate (a) the circuit impedance, (b) the current
flowing, (c) the p.d. across the resistance, (d) the p.d. across the inductance, and (e) the phase angle
between voltage and current.
