4 Ohm Power Resistor Popular Q&A

Q: What is the power dissipated in a 4 ohm resistor carrying 3 amps?
A: Use the formula P = I. 2. R (I = current; R = resistance) Read More »

Q: How would i calculate the power generated in the 4k ohm resistor?
A: The voltage across the 4k resistor is 60v * 4k / (15k + 4k + 11k) = 60v * 4/30. = 8v. Power = V^2/R. Power = 8^2/4k. = 64/4000. = 0.016 watts. = 16mw. Read More »

Q: What is the power when there are 58 m'A of current through a 4.7 ...
A: By Ohm's law, voltage = current times resistance, so 50 mA of current through a 4.7 kOhm resistor yields a voltage drop of 235 volts. By the power law, power = ... Read More »

Q: How much power is dissipated in the 3 ohm resistor?
A: The 3 and 6 in parallel are equivalent to 3*6/(3+6) = 2 ohms. that in series with 4 ohms is equivalent to 6 ohms. Total current is 12/6 = 2 amps. This causes a ... Read More »
