If the maximum voltage across a 100ohms resistor is 20V, then the maximum power it can dissipate is
Answer Details
The maximum power that a resistor can dissipate is determined by the maximum voltage applied to it and its resistance value. The formula for calculating the power is P = V^2/R, where P is power in watts, V is voltage in volts and R is resistance in ohms. Therefore, substituting the values given in the question, we have:
P = (20V)^2 / 100ohms = 400 / 100 = 4.00W
Hence, the maximum power that the resistor can dissipate is 4.00W.
