Question #55898
6 Calculate the currents in \$3\Omega\$ resistor 0.36A 2.54A 1.42A 3.46A 7 Calculate the currents in the circuit 1.94A 1.36A 3.23A 5.45A 8 Electrical energy is sold by PHCN in units of kilowatt-hour (kWh). The lighting of a house is done with five 60W bulbs which are swithed on for approximately three hours per day. What is the lighting bill for the household over a period of 30days at the rate of N1.20 per kilowatt-hour? N1.50 N25.30 N32.40 N52.20 9 A battery has emf 13.2V and internal resistance \$24m\Omega\$. If the load current is 20.0A, find the terminal voltage o f the battery 12.7V 14.5V 16.8V 17.7V 10 A cirrent flows in a wire of circular cross-section with the free electrons travelling with a mean drift velocity v. If an equal current flows in a wire of the same material but of twice theradius, what is the new mean drift velocity? v/4 v/2 2v 4v
