Question

A series R-C circuit is connected to an alternating voltage source. Consider two situations: a. When capacitor is air filled. b. When capacitor is mica filled. Current through resistor is i and voltage across capacitor is V then:, V a > V b, i a > i b, V a = V b, V a V b

​​​​​​​ i = v R 2 + 1 Cω 2 V C = v R 2 + 1 Cω 2 × 1 Cω V C = V RCω 2 + 1 If we fill a di-electric material C ↑ ⇒ V C ↓
