Acircuit consists of a battery and two resistors connected in parallel. if the resistance in both resistors is doubled, and the current is kept constant, how does the voltage change?

a) the voltage is quartered
b) the voltage is halved
c) the voltage remains the same
d) the voltage is doubled

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
