Answer:
The new resistor has resistance of 9Ω.
Explanation:
The effective resistance of three resistance is
.
we know the the circuit with 9V battery has current of 3.6A; therefore, must be
,
which means
Now, Sally wants to connect another resistor in parallel so that the current becomes 4.6A. The resistance required for that is
.
which means the 4th resistor must satisfy the equation
and since
equation (2) becomes
which we solve for :
Thus, the resistance of the new resistor is 9 ohms.
Answer:
The input force is the force that when you push down and the output force is the stable going into the paper.
