In the circuit B, R eq is the total equivalent resistance seen in circuit A. This means that both the circuit B and A batteries have the same current.

What resistance should be used for R in circuit A so that R eq will be 100 ohms?

also, if the battery voltage is 10 volts in circuit A, and the equivalent resistance is 100 ohms, how much power is dissipated by the total resistance in the circuit? and what power is dissipated in each resistor?

please help me with this.

thankyou.
