Question
For the circuit below work the following problems: a) What is the voltage across resistor C? b) Rank the resistors from lowest to highest resistance. c) Rank the currents in the resistors from lowest to highest. d) If the resistors were replaced with light bulbs having similar resistances, rank the brightness of each, dimmest to brightest. 2. For the circuit below work the following problems: The resistors in this circuit are equivalent to the ones in the previous diagram. a) What is the voltage across each resistor? b) Rank the currents in the resistors from lowest to highest. d) If the resistors were replaced with light bulbs having similar resistances, rank the brightness of each, dimmest to brightest. 3. An electron is moving near a long, current-carrying wire, as shown below. What is the direction of the force on the electron?Explanation / Answer
a) using KVL :
e - Va - Vb - Vc = 0
20 - 6 - 8 - Vc = 0
Vc = 6 V
b) all resistors are connected in series so same current will pass through them .
lets say i.
then 6 = i Ra
8 = i Rb
6 = iRc
A = C < B
c) current will be same (series connection)
A = B = C
d) same currents flow in series connection.
and bulb are of same resistance
hence all will have same brightness.
A = B = C
