A discharge tube is connected to a power supply of 200 V . Calculate the effective resistance of the tube if the number of protons drifting through a section per second is 1.5 xx10^(18) and the number of electrons drifting in opposite direction through auother cross section per second is 2.0 xx10^(18) .

The figure given below shows an electric circuit in which current flows from a 6V battery through two resistors. (a) Are the resistors connected in series with each other or in parallel? (b) For each resistor, state the p.d. across it. (c) The current flowing from the battery is shared between the two resistors. Which resistor will have bigger share of the current? (d) Calculate the effective resistance of the two resistors. (e) Calculate the current that flows from the battery.
