Well, the best way is to run it inside the cieling but if that is not an option: The safest way is to run it in conduit. You can buy PVC conduit that is easy to work with at any hardware store. Secure it to the cieling with clamps screwed into studs, not the lath supporting the cieling. Remember: * you can poke holes in the cieling where the pipe will be to find the studs and then hide it with the pipe. * You may also want to consider pre-painting the pipe before installing as the regular sch80 grey isn't very pleasing to the eye. * You'll notice that the pipe has flared ends to join pieces together. Make use of this. Having all the flares going the same way along the pipe will make pulling cable easier, as a cable being pulled through a joint into the flair has nothing to catch on. * This doesn't have to be watertight, so be sparing with the glue. You are only putting it in conduit to protect the wire, not because it is in a harsh enviromnent.
Voltage is impressed across a circuit. Current flows through a circuit.
The high school band marched diagonally across the gym floor.The crack ran diagonally across the basement floor.It's a busy street that runs diagonally through town.For the party, she ran a string of balloons diagonallyacross the ceiling.
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
Parallel circuit.

In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.

A parallel circuit. Since a parallel circuit has only two nodes, there can be only one voltage difference between the nodes.
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
Any part of a circuit that has a voltage drop across it is a resistor.
