1.1.
Ohm’s law relates V, I and R for a resistor. For each of the situations following, find the
missing item:
(a) R=1k
Ω
, V=10V
(b) V=10V, I=1mA
(c) R=10k
Ω
, I=10mA
(d) R=100
Ω
, V=10V
1.3.
Ohm’s law and the power law for a resistor relate V, I, R and P, making only two variables
independent. For each pair identified below, find the other two:
(a) R=1k
Ω
, I=10mA
(b) V=10V, I=1mA
(c) V=10V, P=1W
(d) I=10mA, P=0.1W
(e) R=1k
Ω
, P=1W
1.7.
A tworesistor voltage divider employing a 3.3k and 6.8k resistor is connected to a 9V
groundreferenced power supply to provide a relatively low voltage. Sketch the circuit. What
output voltage (measured to ground) and equivalent output resistance result?
1.15.
Through related application of Thevenin’s theorem, find the Theveninequivalent of the
circuit below between node 4 and ground and hence find the current that flows through a load
resistance of 1.5k connected between node 4 and ground.
1.21.
