chapter 3 :capacitor

When 3 capacitors are arranged in series , the equivalent capacitance C is

• C_eq = C₁ + C₂ + C₃

• 1/C_eq = 1/C₁ + 1/C₂ + 1/C₃

• C_eq = QV₁ + QV₂ + QV₃

• C_eq = CR₁ + CR₂ + CR₃

When 3 capacitors are arranged in parallel , the equivalent capacitance is

• C_eq = C₁ + C₂ + C₃

• C_eq = 1/C₁ + 1/C₂ + 1/C₃

• C = QV₁ + QV₂ + QV₃

• 1/C_eq = 1/C₁ + 1/C₂ + 1/C₃

During charging a capacitor through a resistor

• the current in the circuit increases linearly with time

• the current in the circuit decreases linearly with time

• the current in the circuit increases exponentially with time

• the current in the circuit decreases exponentially with time
