Find out the volume of that object and then the mass of it and divide the mass by the volume to get the density.
Comment:
The answer given above is very wrong(in electricity).
Answer:
Bus bars carry high currents and thus a current transformer is used. It uses the bus bar as its primary winding and its wound section as its secondary winding. The magnetic flux of the bus bar due to its current is very small thus the current in the secondary windings will be small as well and safe to measure with a traditional Ammeter.
NB: These types of work must only be carried out by a qualified electrician. Don't put your life at risk.
Depends on the type of the machine. For each one of them there is a formula that will lead to the capacity of a particular machine.
One way to calculate current is using ohms law; current equals voltage divided by resistance or: I=V/R Where I is current, V is voltage and R is resistance.
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).

To calculate the inductance of a home made inductor simply take the number of turns,the magnetic flux linkage and the current and use the inductance formula.

volts divided by resistance equals maximum amperage (current)
Jc=sigma.E
to fine I (current) when you have R (resistance) and V (voltage) you use the formula: I = V / R
Tis question is incompleet.1000 va =1 kva.This is the power capacity of transformer. A transformer having 2 currents Primary current and secondary current . for that we required both voltage. Simply we can calculate by a formula Voltage x Current x 0.8(power factor)=1000.

The formula you are looking for is I = W/E. Amps = Watts/Volts.
