400 joule of heat is produced in 4 seconds in 4 sisters find potential difference across resistor
Ruchir1234:
is there any other detail like resistors strength or current flowing
no mam
the question is wrong because potential difference is equal to the work done divided by charge and charge is not give
400 j of heat is produced in 4 sec in 4 resistors .find potential difference across the resistor
give and what happened

⇒Q = P×T
⇒Q = I×V×T
⇒Q = (V÷R)×V×T
⇒400J = (V÷4ohm)×V×4SEC
solving
⇒V×V = 400
⇒V = 20v
⇒Q = I×V×T
⇒Q = (V÷R)×V×T
⇒400J = (V÷4ohm)×V×4SEC
solving
⇒V×V = 400
⇒V = 20v
