A capacitor is placed in series with a resistor, and a square wave is applied.
a. Sketch the RC response to the square wave
b. Beneath this, to the same scale, sketch a second wave where R has been doubled and C has been halved
c. Sketch a third wave beneath these where the product RC has been increased by a factor of 4
in series with 8Ω resistance. How much is the total resistance of the circuit?
they are placed vertically and have a uniform
reducing power. The powers of the first,
second, third and fourth resistors are 3000,
2600, 2200, and 1800 respectively. Find the
power of the resistor
