Explanation:
Ginawan ko ng Diagram yung problem para mas madaling maisolve.
So ganito,
May 3 bulbs (yan yung bilog na may x sa loob)
Kada bulb may resistor na may 10ohms na value.
Meaning may Resistance tayo na tatlo.
R1 = 10 ohms
R2 = 10 ohms
R3 = 10 ohms
Voltage = 220 volts
Sa unang tanong, kailangan kunin ang Total Current.
Pero bago natin makuha, kailangan macompute muna natin yung Total Resistance.
Kapag may value na ang Resistance at Voltage (which is given naman). Pwede na isolve ang Current.
So yung Current flowing is 7.33A.
And ang Total Resistance across is 30ohms.
