Answer» Given : a resistor of resistance 40 Ω produce 1000J of heat energy, To Find : the POTENTIAL difference between the two ENDS of the resistor Solution: Heat produced = V²/R Heat produced = 1000 J Resistance = 40 Ω V²/40 = 1000 => V² = 40 * 1000 => V = 200 V potential difference between the two of the resistor = 200V Learn More: If heat DISSIPATED in a resistance can be determined from the relation ... The heating element CONNECTED to 230V draws a current of 5A ... |
