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 value of the current in both bulbs (resistors) is the same or not? Why or why not? Explain in words?


8- If you add the value of the voltage across both bulbs (resistors), is it the same as the voltage (emf) of the battery? Why or why not? Explain in words.

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 parallel. Now record the current through each bulb and the voltage across each bulb.

9- Does the value of the current through each bulb remain the same as in previous setup of a single bulb? Why or why not? Explain in words?


10- Does the value of the voltage across each bulb remain the same as in previous setup of a single bulb? Why or why not? Explain in words?

Expert Solution

Here we assume that each bulb has same resistance. If resistance is different then result is same except question number (9) . I consider that case also in question number (9).

If you feel any problem then comment.

The voltage in a circuit is 115 volts. A particular technique for measuring the voltage gives readings which are normally distributed with mean μ=115 volts and standard deviation 5 volts. Show that the average of four readings has smaller probability of differing from the true value by 3 volts than an individual reading. Hence show that average of several measurement of the same thing is always more accurate than an individual measurement.
