1. A power transmission line is hung from metal towers with glass insulators having a resistance of 2.55 ✕ 109 Ω. What current (in mA) flows through the insulator if the voltage is 280 kV? (Some high-voltage lines are DC.)

2. A charge of 6.50 C passes through a pocket calculator's solar cells in 2.00 h. What is the power output (in W), given the calculator's voltage output is 4.50 V?
