Question

The glow of the indicator bulb indicates in the given circuits-

a. that the resistors are in series

b. the effect of additional resistors upon the overall current

c. the number of bulbs in connection

d. the presence of current in the circuit​

Answer 1

b. the effect of additional resistors upon the overall current is the correct answer.

• The given diagram indicates that the indicator bulb glows more brightly on addition of resistors. All the resistors are added in parallel.
• As is already known, voltage remains constant in the parallel connection, and increase in resistance gives an overall decreased resistance.
• Thus, the current increases and hence the indicator bulb grows birghter.

Answer 2

Answer:

the effect of additional resistors upon the overall current
