a.
Answer to Problem 11CFU
4 seconds
Explanation of Solution
Given information:
The graph for simple electric circuit between power supply i.e. current
When power supply is off, there is no current in the circuit.
When power supply is on, the current almost instantly becomes a constant value.
Calculation:
From the graph, the current is 0 amps as
b.
To find: time when was power supply turned on.
b.
Answer to Problem 11CFU
After 4 seconds
Explanation of Solution
Given information:
The graph for simple electric circuit between power supply i.e. current
When power supply is off, there is no current in the circuit.
When power supply is on, the current almost instantly becomes a constant value.
Calculation:
The graph shows that current increased from 0apms to 10amps at
c.
To find: the current in the circuit for the given situation.
c.
Answer to Problem 11CFU
10amps
Explanation of Solution
Given information:
The given condition is that a person left the power supply on for hours.
The graph for simple electric circuit between power supply i.e. current
When power supply is off, there is no current in the circuit.
When power supply is on, the current almost instantly becomes a constant value.
Calculation:
As it given that the current almost instantly becomes constant when power supply is on. So even if the person left power supply on even for hours, the current should be still 10amps.
