Question

Written homework, due at star of studio 4b Consider the complicated network of resistors drawn at the right In the question below the EMF of the battery is always the same, it does not change. In thinking about the question there is a general principle you may use (which w surprisingly hard to prove): if the resistance of any resistor in the network increases then the equivalent resistance of the entire network increases All your answers should be either "Increases", "stays same", or "decreases". If R1 increases then how does the current through R3 change? If R2 Increases then how does the current through R2 change? If R2 increases then how does the current through R3 change?

Explanation / Answer

IF R1 INCREASE TOTAL CURRENT IN LOOP DECREASES,CUURENT WILL ALSO DECREASE IN R5. IF R2 INCREASES THEN CURRENT THRU R2 WILL DECREASE. IF R2 INCREASES CURRENT THU R3 WILL INCREASE
