Measuring Current and Voltage:
Make a circuit consist of a battery and a bulb. Measure
and record the voltage across the bulb and the current through the
bulb. Now attach another bulb in series. Now record the current
through each bulb and the voltage across each bulb.
6- Does the value of the current through each bulb
(resistor) remain the same as in the previous setup of a single
bulb? Why or why not? Explain in words?
7- Does the...

Draw an experiment circuit to produce and measure a 5 kA peak
lightning impulse current. In the test circuit, determine the
methods of measuring the pulse current, determining the element
values and properties according to the current to be measured.
Describe one of the methods.
