Hello everyone

My last question may be a little misleading and I couldn't respond to my own question so please forgive me when I rephrase it again.

I have a 65w stepdown Input230/240 AC, Out: 115V AC. 65VA transformer and I wanted to know if I should be concerned about how much electricity the transformer draws just by the fact that it is plugged into the wall socket even when the hardware connected to it is not on.

I don't need an exact figure. Just a layman's terms as what your typical transformer would draw. An absolute average idea of the average transformer.

If I turn the transformer off, all my appliances will need to be reset when I turn the transformer back on again.

So does an average one consume as much as a light bulb, or say... something much more.. like a computer etc.

I just need a general idea. Thank you.

If a woman drives from home straight to work at an average speed of 480/13 mph., she arrives at work 1 minute late. However, if the woman drives from here home straight to work at an average speed of 40mph., she arrives at work 1 minute early. Find the number of miles from the woman's house straight to work.
Thanks,

The air flow exhausted out of a room with dimensions 30’ x 30’ x 10’ is 4500 cfm. Calculate the number of air changes per hour. What do you know about the relative safety of this room with regard to the concentration of a solvent evaporating in this room, based on the ACH value? What happens to the number of ACH if the room volume was half the original amount? What does this changed ACH tell you about the concentration in the smaller room compared to the larger room, at equilibrium conditions?

My wife was transported by ambulance to a local Speciality Hospital and was admitted to the E.R for a unstable anginia or heart problems. She stayed in the E.R. for 2 tp 3 hours and then was transfered to CCU and a couple of hours after that she had a masive heart caused by a blood clot and died. Would that be considered medical mal-practice?
