Is it true a transistor changes alternating current into direct current?
Not usually. A transistor is an amplifier, that can be used as a switch. If set up correctly it can be used to rectify AC current (i.e. convert it into DC), however it will need a capacitor to smooth the DC current (i.e. keep the voltage constant or nearly the same). What is typically used is a rectifier, a small circuit consisting of one or more diodes.
What is a current consisting of charges that flow only in one direction called?
A current consisting of charges that flow only in one direction is called direct current (DC). In DC, electrons flow continuously in one direction from the negative to the positive terminal of a power source.
When discussing electrical current what does DC stands for?
When discussing electrical current, DC stands for Direct Current (a current where the electron flow in the wires goes only one way)
Battery ac or DC?
Batteries can provide both AC (alternating current) or DC (direct current) power, depending on the type of device they are connected to. However, most batteries themselves supply DC power. Devices that require AC power typically use an inverter to convert the battery's DC power into AC power.
Is a AC adapter the same as a charger?
An ac adapter converts ac current into dc current through a rectifier, and a battery charger outputs dc current at an adjustable powerful charging rate and also converts ac current to dc current to charge different sizes of batteries.
Which is not true for a DC circuit?
... Current surges back and forth.
When you stepup ac voltage the current drops.What will happen with CURRENT if DC is stepped up?
WHEN YOU STEP UP THE VOLTAGE AND THE LOAD IS THE SAME MORE CURRENT WILL FLOW NOT LESS. AND THAT WILL HOLD TRUE FOR DC AS WELL. IF THE LOAD REMAINS THE SAME AND YOU INCREASE THE CURRENT AC OR DC THE VOLTAGE WILL INCREASE
Why dc current is called direct current instead of direct current current?
dc is an abbreviation for direct current. The term dc current is sort of wrong it's a bit like saying something twice for no reason.It might be better to say dc electricity rather than dc current.AnswerIn electrical engineering, it is normal to use the terms, 'd.c. current' and 'd.c. voltage', because the abbreviation, 'd.c.' is considered to be an adjective. The same is true for 'a.c.', too.
Which of the following is true regarding current scientific thought?
RNA originated before DNA
How DC generator produces DC current from ac current?
DC GERATORS PRODUCE DC current with the help of spilt ring commutators.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Which is the device that converts AC to DC?
A Rectifier converts Alternating current into Direct current
If it true that ac current can pass through the capacitor while dc current can not?
In case of DC: because the frequency of dc current is zero capacitive reactance ( Xc) = 1/2(22/7)fc f= frequency c=capacitence and when Xc=0 this implies that I=0 In case of AC: Xc >0 => I>0
Is it true that a battery produces alternating current?
No. A battery produces DC, or Direct Current.
What is the sign for ac and DC current?
AC means alternating current DC means direct current there is no polarity reversal
What are the two kinds electricity?
Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.
