Question 1 The energy stored in a capacitor when a voltage V is applied is U. When the voltage is doubled, the energy stored by the capacitor is: Question 1 options: U4 The energy stored by a capacitor does not depend on the applied voltage U2 4U 2U Suppose you have two long parallel wires, the first with current i1-820 mA and the second with i2=525 mA both going in the same direction. If the wires are 5.0 cm apart, then what is the magnitude of the force per metre on wire 2 due to wire 1? Question 2 options: 2.1x10-6 N/m 1.7x10-6 N/m 3.3x10-6 N/m 3.4x10-5 N/m 8.6x10-8 N/m
