A current flows through a conducting material such as copper wire when it is connected to the positive and negative terminals of a battery, which applies an electrical potential difference or voltage. Electrons in the wire then drift towards the positive terminal. National electricity grids deliver ...
aThe power P released from a battery when current I flows between the battery terminals with a voltage difference of V is expressed by the following equation: 从电池P发布的力量,当潮流I流动在电池终端之间以V时电压区别由以下等式表达:[translate]...
Four 18.0 {eq}\Omega {/eq} resistors are connected in parallel across a 25.0 V ideal battery. What is the current through the battery? Resistors in Series: If a certain number of resistors are connected in series (in a circuit), then we...
aIf a battery is connected across a conducting material,a certain amount of current will flow through the material.This current is dependent on the voltage of the battery,on the dimensions of the sample,and on the conductivity of the materials itself. 如果电池横跨举办的材料连接,一定数量潮流将流...
The current passes through a resistor in a circuit connected across a battery of the potential V is equal to the ratio of the supplied voltage and resistance. As we increase the potential of the battery, the current in the resistor directly increases. Thus, {eq}...

Again, it would just be a different interpretation of this poorly-worded question. Now, on to Part ii). My interpretation is that the is the internal resistance of the battery when the switch is closed (and thus a specific amount of current is flowing through the battery). In that case ...
8.A closed path followed or capable of being followed by an electric current.电路一个通过电流或可通过电流的封闭路径 9.energize a battery by passing a current through it in the direction opposite to discharge.通过电流朝与放电相反的方向流动给电池充电。
aThe current from the battery is flowing through the wire on both sides of the wire form. This creates a magnetic field around the wire. This field interacts with the field from the cube magnet and the disks. The wire's field creates a force at right angles to the field from the magnet...
