In the MKS system of units, the volt is defined by
(A) 1V = 1N/C.
(B) 1V = 1J/C
(C) 1V = 1C/N
(D) 1V = 1C/J
In the MKS system of units, the volt is defined by
(A) 1V = 1N/C. --- No.
That is the unit of field strength.
In the MKS system of units, the volt is defined by
(B) 1V = 1J/C --- Yes.
energy per unit charge.
In the MKS system of units, the volt is defined by
(C) 1V = 1C/N --- No.
Electrical units are things per charge.
In the MKS system of units, the volt is defined by
(D) 1V = 1C/J --- No.
Electrical units are things per charge.
The potential energy of a charge of 3 micro-coulombs in a potential of 2 million volts is
(A) 1J.
(B) 2J.
(C) 3J.
(D) 6J.
The potential energy of a charge of 3 micro-coulombs in a potential of 2 million volts is
(A) 1J. --- No.
Calculate the answer.
The potential energy of a charge of 3 micro-coulombs in a potential of 2 million volts is
(B) 2J. --- No.
Multiply the numbers together.
The potential energy of a charge of 3 micro-coulombs in a potential of 2 million volts is
(C) 3J. ---No.
Multiply the numbers together.
The potential energy of a charge of 3 micro-coulombs in a potential of 2 million volts is
(D) 6J. --- Yes.
The electric potential of a point is defined only if
(A) the point is in contact with matter.
(B) there is unbalanced charge at the point.
(C) the position of the point is defined.
(D) unbalanced charge is near the point.
The electric potential of a point is defined only if
(A) the point is in contact with matter.
No. Contact is not needed.
The electric potential of a point is defined only if
(B) there is unbalanced charge at the point.
No. Charge is not needed.
The electric potential of a point is defined only if
(C) the position of the point is defined.
Yes, Electric potential is a property of space alone.
The electric potential of a point is defined only if
(D) unbalanced charge is near the point.
No. Unbalanced charge is not needed.
(A) both feet on a grounded rail.
(B) both feet on the third rail.
(C) one foot on the third rail and one foot on another rail.
(A) both feet on a grounded rail.
No. No potential difference, no problem.
(B) both feet on the third rail.
No. No potential difference, no problem.
(C) one foot on the third rail and one foot on another rail.
Yes. 600V potential difference between feet is unhealthy.
