The power dissipated in resistor `R` is `16R` wat, whether the switch `S` is closed or open. The unknown e.m.f `epsilon` in the circuit is

If the power dissipated in the circuit is 4W then the value of R is:

If the power dissipated in the circuit is 4W then the value of R is:

If the power dissipated in the circuit is 4W then the value of R is:

In the R-C circuit shown in the figure the total of 3.6 xx 10^(-3)J is dissipated in the 10 ohms resistor when the switch S is closed. The initial charge on the capacitor is

In the given circuit the power dissipated through resistance R_(1) = 9 Omega is P_(1) , when switch S_(1) is closed and S_(2) is opened and the power dissipated through resistance R_(2) = 4 Omega is P_(2) , when switch S_(2) is closed and S_(1) is opened. If P_(1) = P_(2) , then r is equl to :

In the given circuit the power dissipated through resistance R_(1) = 9 Omega is P_(1) , when switch S_(1) is closed and S_(2) is opened and the power dissipated through resistance R_(2) = 4 Omega is P_(2) , when switch S_(2) is closed and S_(1) is opened. If P_(1) = P_(2) , then r is equl to :
