WebOf course, the direction of current is controlled by the polarity of the voltage. So in order to change the direction of rotation, we can simply reverse the voltage, causing the current to flow in the opposite direction, changing the force by 180 degrees and the motor to be driven ‘backwards’. What damage can reverse polarity cause? WebYou can define the voltages and the currents any which way you like, but you have to make sure that the signs between voltage and current across the resistor are proper.

WebIn the realm of electronics, polarity indicates whether a circuit component is symmetric or not. A non-polarized component -- a part without polarity -- can be connected in any direction and still function the way it's supposed to function. A symmetric component rarely has more than two terminals, and every terminal on the component is equivalent. WebFeb 13, 2016 · A resistor is a passive two-terminal electrical component that limits the current flowing in electrical or electronic circuits. Its property to resist the flow of current is called resistance, expressed in ohm (Ω), named after German physicist Georg Simon Ohm. Resistors are available in different sizes.
