Hello students here is a given question and the question says two lengths, one rated 100 watt, means the p1 is equal to given 100 watt and p1 is given that will be equal to 220 volts.
00:14
And p2 is given that is 60 watt and v2 is given that is 220 volt.
00:21
Are connected in parallel to electric main supply.
00:26
Then what current is drawn from the line if a very much.
00:30
The supply voltage is 220.
00:32
First, we have to find out the r1 and r2.
00:36
What is the r1 and r2 here? we know that the r1 is equal to v squared divided by p, then b1 squared divided by p1 and this will be v2 squared divided by p2 to solve this, then r1 equals to.
00:49
What is the b? that is the 220 multiplied by the 220 divided by p is 100.
00:55
After solving this, we get r1 is equal to 4 ,8, 4 .4.
01:00
And what is the r2? r2 will be equal to this will be 2 to 0 multiplied by the 220 divided by 60.
01:08
After solving this, 2 2 this is 3 times, 2 to this is 11 times.
01:13
Then it will be equal to r2 will be equal to 0, 11 to the 22 and 22 that is 24 and divided by 3 o 'em...
