Question

The circuit given has a battery, an ammeter, and a collection of resistors. What happens to the current through R_6 if R_2 is decreased? The current increases. The current decreases. The current stays the same You are building an electric heater. You have a 20V power supply and wish to produce 100 times J/S How much current must flow through the device? 1/5A 5A 20A 100A 2000AYou have two resistors of resistance 1 omega and 2 omega. What is the complete set of possible resistances you can form by either using one or both of the resistors? 1 omega, 2 omega, 3 omega 1 omega, 2 omega, 3 omega, 1/2 omega 1 omega, 2 omega, 3 omega, 1/2 omega, 3/2 omega 1 omega, 2 omega, 2/3 omega 1 omega, 2 omega, 3 omega, 2/3 omega

Explanation / Answer

R2 and R3 are in parallel connection

so if we decrease the magnitude of the R2 resultant resistance across circuit will decrease

by ohm's law

V = IR

so if the resistance will decrease the current will increase to maintain the same potential

so the current through R6 will increase
