a) What is the current in the hot plate?Answer in units ofA. A microwaveoven connected across a potential difference of 126 V has aresistance of 39 .
b) What is the current in the microwave oven? Answer in units ofA. A hot plate connected across apotential difference of 126 V has a resistance of 67.
a) What is the current in the hot plate?Answer in units ofA. A microwaveoven connected across a potential difference of 126 V has aresistance of 39 .
b) What is the current in the microwave oven? Answer in units ofA.

Explanation / Answer

a ) Potential difference across a hot plate is V   = 126 V                              resistance R = 67      current in the hot plate is I = V / R                                                = 126 V / 67                                                 = 1.88 A b )   Potential difference across the microwave oven is V = 126 V                              Resistance R = 39                   current I = V / R                                  = 126 V / 39                                  = 3.23 A
