题目内容

A meter used to measure amperes is called ______ (a/an) _______ (ammeteroltmeter).A voltmeter should be connected to the circuit being tested ___________________ (in series/in parallel).In a series circuit the voltage is ___________ (dropped) or lowered by each resistance in the circuit. The higher the resistance, the greater the ___________ (drop/rise) in voltage.If the voltage increases in a circuit, the current ____________ (increases/decreases) if the resistance remains the same. The symbol for voltage used in calculations is ________ (U/I/R).Today, the term, mechatronics, __________________ (encompassed/compassed) a large array of technologies, many of which have become in their own right. A _____________ (parallelries) circuit is a complete circuit that has more than one path for the current to flow, most of the ___________ (voltage/current) will flow through the branch with the lower resistance.Cycles per second are expressed in _________ (Hertz/Pulse width).
