Two parallel flat plates are separated by 2cm. A voltage of 500 V is applied to the parallel plates. What is the maximum electric field force experienced by an electron passing between the plates?
the rms current through the 45-ohm resistor in the circuit shown is
the current in the 100 ohm resistor is
first solve first loop:
and then find I=V/R
and then Is=(N1/N2)*IP
A copper conductor 10 m long and 3mm in diameter has a resistance of 0.024 ohms at room temperature (20C). What is the temperature in degrees Celsius if this conductor has a resistance of 0.036 ohms? (∝=0.0039)
solve for T=148
the instantaneous current through the inductor at t=0.001 sec in amperes is

An A/D converter has a range of -5V to 5V and 8 bit output. An output of 01101100 corresponds approximately to what input voltage?
voltage range (-5V to 5V)=100
10/256= 0.0391 volts/steps
0.0391 volts/steps*108 steps=4.228
-5V+4.228= -0.7772 volts
