Physics Problems - Lab Report ExampleWhen resistors are connected in parallel, their terminals are connected across the potentiality source, and the voltage drop across each terminal is the same. But, if the value of resistors is different, the current through the resistor will be different, and accordingly the power fast by the resistor will be different.Step-Up Transformer Such a transformer, steps up the voltage at the secondary windings. In such a transformer, the number of turns in secondary windings is more than that in primary windings. The proportion in which voltage will be stepped up depends upon the proportion in which the meter of windings are more in the secondary windings.Step-Down Transformer As the name suggests, step mound transformer is utilise to lower the voltage. In such a transformer, the poesy of turns in secondary winding are less than the number of turns in primary. If the numbers of turns in the secondary are half than the primary, then the voltage in the secondary will be half of the primary voltage. Therefore, transformer is a useful device used in AC circuits for dividing or multiplying the voltage levels.This run is in addition applicable to electrically charged particles. Two like charges repel each other while two opposite charges attract each other. The force amid the charged particles is defined by the Coulombs law.... In such a transformer, the number of turns in secondary windings is more than that in primary windings. The proportion in which voltage will be stepped up depends upon the proportion in which the numbers of windings are more in the secondary windings. Voltage transformation ratio = (Number of turns in secondary-N1) / (Number of turns in primary-N2)For example, If the number of turns in secondary windings are double than primary winding than the voltage will be doubled.Step-Down Transformer As the name suggests, step down transformer is used to lower the voltage. In such a transformer, the numbers of tur ns in secondary winding are less than the number of turns in primary. If the numbers of turns in the secondary are half than the primary, then the voltage in the secondary will be half of the primary voltage. Therefore, transformer is a useful device used in AC circuits for dividing or multiplying the voltage levels. Q. Explain how the rule for the interaction amongst magnetic poles compares to the rule for interaction between electrically charged particles.Ans. The rule for interaction between magnetic poles states, Opposite magnetic poles attract each other while similar poles repel each other.This rule is similarly applicable to electrically charged particles. Two like charges repel each other while two opposite charges attract each other. The force between the charged particles is defined by the Coulombs
