An external resistance R is connected to a battery of e.m.f. V and internal resistance r . The joule heat produced in resistor R is maximum when R is equal to

Find the value of i_(1)//I_(2) in figure if (a) R=0.1(Omega) (b) R=1(Omega)(c) R=10(Omega) .Note from your answers that in order to get more current from a combination if two batteries they should be joined in parallel if the external resistance is small and in deries if the external resistance is large as compared to the internal resistances.

A cell to emf. E and internal resistance r supplies currents for the same time t through external resistance R_1 and R_2 respectively. If the heat produced in both cases is the same, then the internal resistance is given by :

Assertion: Syngamy occurs in the external medium, i.e. the outside of the body of the organism is called external fertilisation. Reason: Syngamy occurs inside the body of organism is called internal fertilisation.

Two identical batteries each of emf E= 2 volt and internal resistance r=1 ohm are available t . produce heat in an external resistance by passing a current through it. What is the maximum power that can be developed across an external resistance R using these batteries?

Two identical batteries, each of e.m.f. 2 volt and internal resistance 1.0 ohm are available to produce heat in an external resistance R = 0.5 ohm by passing a current through it. The maximum Joulean power that can be developed across R using these batteries is
