Question

What is the maximum rated voltage for a 100 ohm 1/4 watt resistor?

Answer 1

The maximum rated voltage for a 100 ohm 1/4 watt resistor is 5 volts, calculated using the power formula and rearranging it to solve for voltage.

Step-by-step explanation:

The maximum rated voltage for a 100 ohm 1/4 watt resistor can be calculated using the formula for power (P), which is P = V^2/R, where P is power in watts, V is voltage in volts, and R is resistance in ohms. Rearranging the formula to solve for V, we get V = sqrt(P * R). By plugging in the given values (P = 0.25 watts, R = 100 ohms), we find V = sqrt(0.25 watts * 100 ohms), which gives us V = 5 volts. Therefore, the maximum rated voltage for the resistor is 5 volts.

Answer 2

this can be solve using the formula P = I^2 * Rwhere P is the powerI is the CurrentR is the resistanceP = I^2 * R
1/4 Watt = I^2 * 100 ohm solve for II^2 = 1/400 I = 0.05 amps then using the formula to solve for the voltage:V = I * RV = 0.05 amps * 100 ohms V = 5 volts
