1. The current in the circuit is 5 kiloamperes (KA). 2. The resistance is 0.25 ohms (Ω). 3. The current is 2 milliamperes (mA).

1. Desarrollo: B. 5000 A a KA
1. A. 10V a mV 1000 A = 1 KA
1V = 1000mV 5000 A = x
10V= x 5000 * 1 / 1000
10 * 1000 / 1 5KA
= 10000mV 4. A. 5000000W a MW
B. 10V a KV 1000000W = 1MW
1000V = 1KV
5000000W = x
10V= x
5000000 * 1 / 1000000
10 * 1 / 1000
5MW
= 0.01
B. 73KW a W
2. A. 50Ω a mΩ
1KW = 1000 W
1Ω= 1000mΩ
73KW = x
50Ω= x 73 * 1000 / 1
50 * 1000 / 1 = 73000 KW
= 50000 mΩ
B. 250mΩ a Ω
1000mΩ = 1Ω
250mΩ = x
250 * 1 / 1000
= 0.25 Ω
3. A. 2 A amA
1 A = 1000 mA
2A=x
2 * 1000 / 1
2000mA
