2.Two resistors of 5 ohms and 20 ohms are connected in parallel across an ideal source of 20 V. The current supplied by the source is a) .4 A, B) 5 A c) 20 A d) 1 A e) none of these My work R1 = 5 ohms R2 = 20 ohms V = 20 v I = ? V = IR V/R = I = 20 V / 114 ohms = 80 amps 3. The problem statement, all variables and given/known data[/b] Two 2 ohm resistors are in parallel. What is their equivilant resistance? 1/2 ohms + 1/2 ohms = 1 ohm. Is this correct? 4)A 20 volt potential is applied across a series combination of a 10 ohm and a 30 ohm resistor. The current in the 10 ohm resistor is a) .5 amps, b) .67 amps c) 1.0 amps d) 2.0 amps P = I^2R I = THE SQUARE ROOT OF (R/P) I = THE SQUARE ROOT OF (10 ohms/20 V) 5) a 120 volt home electrical socket has 3 wires. How many of these wires would give yo ua shock if you were grounded when yo utouched them one wire at a time? a) one b) two c) three I think it is one.
