A 9.0 V battery is connected to four light bulbs (It has four resistors 2 ohms, 4 ohms, 4ohms, and 6 ohms). Find the equivalent resistance for the circuit and the current in the circuit. Use the equivalent resistance to determine the total power dissipated by the resistors in the circuit.

When two identical resistors are connected in series to a 100 V voltage source, the current is measured to be 7 mA. Now suppose the resistors are connected to the voltage in parallel. Find the power supplied by the source. (in W) OA: 2.800 B: 4.060OC: 5.887 OD: 8.536 OE: 1.238×10¹ OF: 1.795×10¹ OG: 2.602×10¹ OH: 3.773x10¹
