In the following circuit, determine the total resistance, total circuit current, and voltage across each resistor. 9 V R1 = 8 Ω R3 = 20 Ω R4 = 52 Ω R2 = 16 Ω 6. The total current in this circuit is 4 amps. Determine the resistance of R 5 . 24 V R1 = 4 Ω R3 = 8 Ω R2 = 4 Ω IT = 4 A R4 = 10 Ω R5 = ? 7. In the following circuit, determine the total resistance, total circuit current, and voltage across each resistor. R2 = 2 Ω R4 = 5 Ω R1 = 1 Ω R5 = 3 Ω R6 = 40 Ω R3 = 3 Ω 120 V Critical Thinking 1. Explain electromagnetic induction in your own words. Give an example of a case where electromagnetic induction would generate an electric current. 2. How would you create a circuit with multiple bulbs if you wanted to be sure that if one bulb burns out, the remaining bulbs remain lit?
