Question

Use the pictures on the right for the next nine questions. You are given the circuit to the right where all resistors had the same resistivity. Given the original circuit, rank the bulbs in order of their brightness (amount of current) in the box below. Note any bulbs that have an equal amount of current. High Brightness/Current Low Brightness/Current Suppose bulb A were removed and replaced with a wire. When this happens the brightness (and current) of bulb B will_________. decrease stay the same increase

Explanation / Answer

5) at B current I = V/R

at C current I = V/2R and at D current I = V/2R

power P = I^2*R

so A>B>( C=D )

6) A removed then current increases so power  increases

ans C
