Question
Consider the circuit shown on the ngni. a. Are the bulbs C, D, and E connected in series, parallel or neither? Explain. b. Rank the bulbs in order of brightness. Use the symbols 5.,, and .. Explain your ranking. c. How will the brightness of bulbs A and B change if bulb C is unscrewed? Will the result be different if bulb D or E is unscrewed instead? Explain. 8. Consider the circuit shown on the right. Rank the brightness of the bulbs in the circuit. Use the symbols =, . Explain your - ranking. In the two circuits below, the batteries and all bulbs are identical. Compare the current in the circuit on the left to the current in the circuit on the right. Be as quantitative as possible.Explanation / Answer
7) they are connected in parallel as teh voltage across those 3 bulbs are the same
brightness of bulb A=B>C=D=E as teh brightness of a bulb is propotional to the square of the current flowing in it
when c unsrewed brightness of the all the bulbs is same as same amount of current flows through them
8)A>B>C>D=E same reason as in the above question britness propotional to the square of the current
9)current in the left circuit is 3 times the current in the right circuit this can be solved by just replacing a resistor of same resistance say R in the place of all the bulbs in both the circuits
