Answer:
8 ohms
Explanation:
The two resistors of 2 ohms each are connected in parallel so their equivalent resistance becomes
2*2/2+2=4/4=1 ohm
Now this 1 ohm resistance is in series with the other two resistors
Therefore resultant resistance becomes
3+1+4=8 ohms
Each of those choices has some truth to it, but three of the five choices also include some nonsense.
A. The voltage <em>divides proportionally</em> among all resistors in the circuit.
<em>B. </em> As more resistors are added, the current will decrease. <em>True,</em> because the total resistance will increase.
C. The <em>sum </em>of the voltage drops will be the total voltage in the circuit.
D. The current is the same <em>through</em> all resistors in the circuit.
<em>E.
</em> The equivalent resistance will be greater than the individual resistors. <em>True,</em> because the equivalent resistance is the sum of the individual resistors.
