A 1.3uF capacitor is connected to a 1.5 V battery. What is the charge on the capacitor? PREPARE Charge flows through the battery from one capacitor electrode to the other until the potential difference AVc between the electrodes equals that of the battery, or 1.5 V. SOLVE The charge on the capacitor is given by Equation 21.18: 2.0 x 10-6 C 0-CAVe (1.3 x 10-6 (1.5 v) ASSESS The small charge is expected for the small capacitance and the small voltage. and halve the potential difference, the new charge on the positive plate would be Value
