capacitor & capacitors

The figure to the right represents:

• Capacitor
• Diode
• Inductor
• Resistor

With respect to the capacitor, which relationship is true?

• C = Q/V
• V = C×Q
• Q = C/V
• Q = V/C

When capacitors in parallel (3 capacitors), the equivalent capacitance is

• C = C₁ + C₂ + C₃

• C = 1/C₁ + 1/C₂ + 1/C₃

• C = QV₁ + QV₂ + QV₃

• C = QV₁ + QV₂ + QV₃

If 4μF and 2μF capacitors are conneced in series, the equivalent capacitor is ___________.

• 1.33μF

• 0.75μF

• 6μF

• 2μF

Capacitor C₁ and C₂ are connected in parallel. The equivalent capacitance is given by: 

• C₁ + C₂
• 1/(C₁ + C₂) 
• C₁C₂/(C₁ + C₂) 
• (C₁ + C₂)/C₁C₂
