If all meters are ideal and reading of voltmeter 3 is 6V. Power supplied by voltage source is -
Text Solution
Verified by ExpertsThe correct answer is:
D
Current through 20W = 
current through 10W = 
Total current supplied by voltage source
= 
+ 
= 27 Volt
Voltage of battery = 6 + 27 = 33 volt
Power supplied = 
× 33
= 29.7 or 30 Watt
