Answer:
The corresponding magnetic field is
Explanation:
From the question we are told that
The electric field amplitude is
Generally the magnetic field amplitude is mathematically represented as
Where c is the speed of light with a constant value
So
Since 1 T is equivalent to
Answer:
which corresponds to the second option shown: "voltage times amperage"
Explanation:
The electric power is the work done to move a charge Q across a given difference of potential V per unit of time.
Since such electrical work is the product of the potential difference V times the charge that moves through that potential, and this work is to be calculated by the unit of time, we need to divide the product by time (t) which leads to the following final simple equation:
Notice that we replaced the quotient representing charge per unit of time (Q/t) by the actual current running through the circuit.
This corresponds to the second option shown in the question: "Voltage times amperage".
