Question

21. A resistor has a resistance of 176 ohms. How many of these resistors should be connected in parallel so that
their combination draws a current of 5 amperes from a 220 volt supply line ?
22. An electric heater which is connected to a 220 V supply line has tyyn resistance
resistance each. These coilo​

Answer 1

Answer:

7744

Explanation:

Here,

Current,I=5A

Volt,V=220V

Resistance,R=V/I

=220/5

=44hmbs

now,1/R=X/176

1/44=X/176

X=7744
