Ammeter connected in a circuit
Ammeter connected in a
circuit with one dry cell
Q1. What is
the
reading
on the
ammeter?
Ammeter
connected in a
circuit with two
dry cells
Q2. Compare the brightness of the bulb
with one dry cell to its brightness
when there are two dry cells in the
circuit.
Q3. What is the ammeter reading this
time?
Q4. What can be inferred about the
current passing through the bulb?
Connect the
voltmeter as
shown in figure 5.
Switch on and
record the voltage
in Table 1. Once
the task is done,
turn off the switch.

Q5. What is
the
voltmeter
reading?
Add another dry cell
to the circuit. Record
the voltmeter
reading in Table 1.
Observe the
brightness of the
bulb. Once the task
is done, turn off the
switch.
