What is galvanic isolation transformer?
A galvanic isolator is a device which blocks low voltage DC currents coming on board a boat. The reason why these currents are blocked, they cause corrosion to metal underwater.
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
How capacitor and resitor in a circuit effect the phase of input voltage?
A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.
An increase in resistance in a circuit will cause?
In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.
What is the overheating voltage of an electric motor?
Motors overheat due to excessive current, not necessarily voltage. Normal voltage can cause a motor to overheat if it is stuck (not spinning). The problem is not usually the voltage, but whatever is causing excessive current flow (usually because the motor is not spinning like it is supposed to).
When the voltage is increased or decreased what effect does it have on the KVA rating?
Usually increase will cause the KVA levels to come up, especially when you have a decent amperage...
In which direction does the coriolis effect cause currents in the northern hemisphere to turn?
it's to the right.
What direction does the Coriolis effect cause currents in the northern hemisphere to turn?
In the northern hemisphere, the Coriolis effect causes currents to turn to the right. This means that ocean currents tend to flow clockwise in the northern hemisphere as a result of the Coriolis effect.
What is a galvanic?
A galvanic isolator is a device which blocks low voltage DC currents coming on board a boat. The reason why these currents are blocked, they cause corrosion to metal underwater.
What is the cause of oceanic currents?
Ocean currents are caused by various factors. They are made from earthquakes, winds, tides and differences in density. The currents of the ocean have an effect on the weather.
Is longshore drift the cause or effect of a longshore current. Explain?
effect. longshore drift is the combined effect of sediments moved by longshore currents and and beach drift. longshore currents are ocean currents that flow parallel to the coast while beach drift is the resultant zigzag movement along the beach.
What happens to the brightness of a bulb if the volts are increased?
The electrical potential energy increases as the voltage is increased. It further excites the filament in the bulb more than a lessor voltage would. Using good old ohm's law (Voltage = Current x Resistance), a larger voltage applied to a bulb at the same resistance increases the current proportionally and larger currents has the effect to cause higher temps in conductors

What effect does convection currents in people and animals?
It effects the tempreature and can cause hazadurs weather (mind my spelling)

What are 3 things that cause surface currents?
The three factors which control surface currents are the following:Global windsContinental deflection and temperatureThe Coriolis effect
