In an electrical circuit, the voltage is the force that pushes electric current through the circuit. The electrode is the conductor that allows the current to flow. The relationship between voltage and electrode is that the voltage creates a potential difference between the electrodes, which drives the flow of electrons through the circuit.

What is the negative electrode of a voltaic cell called?
The negative electrode of a voltaic cell is called the anode. It is where oxidation occurs as electrons are released into the circuit.
How a carbon-zinc dry cell supplies electric current for a CD player?
A carbon-zinc dry cell supplies electric current by converting chemical energy into electrical energy through a chemical reaction between the carbon rod (negative electrode) and the zinc can (positive electrode). When connected in a circuit, electrons flow from the anode (zinc) to the cathode (carbon), generating a flow of electric current. This current can power a CD player by providing the necessary energy to operate its electronic components.
What does the carbon rod in a standard D-cell serve as?
The carbon rod in a standard D-cell battery serves as the positive electrode, or cathode. It helps to facilitate the flow of electrons from the battery to the connected device, completing the circuit and providing electrical power.

What must the electrodes of a cell have in order for it to produce a current?
The electrodes of a cell must be made of conductive materials to allow for the flow of electrons. One electrode must be a source of electrons (anode), while the other electrode must accept electrons (cathode) to complete the circuit and allow current to flow. Additionally, the electrodes must be immersed in an electrolyte that facilitates the movement of ions between the two electrodes.
What is the difference between a cathode and an anode in an electrical circuit?
In an electrical circuit, the cathode is the negatively charged electrode, while the anode is the positively charged electrode. The flow of electrons is from the anode to the cathode.
What is the difference between the cathode and anode in an electrical circuit?
In an electrical circuit, the cathode is the negatively charged electrode, while the anode is the positively charged electrode. The cathode attracts electrons, while the anode releases electrons.
What is the difference between a cathode and an anode in terms of their functions in an electrical circuit?
In an electrical circuit, the cathode is the negatively charged electrode where electrons flow out, while the anode is the positively charged electrode where electrons flow in. The cathode emits electrons, while the anode receives them.
What is the relationship between wire inductance and the efficiency of an electrical circuit?
The relationship between wire inductance and the efficiency of an electrical circuit is that higher wire inductance can lead to lower efficiency in the circuit. Inductance causes energy losses in the form of heat, which can reduce the overall efficiency of the circuit by wasting energy. Minimizing wire inductance can help improve the efficiency of the electrical circuit.
What is the relationship between volts per amp in an electrical circuit?
The relationship between volts and amps in an electrical circuit is defined by Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R) in the circuit. In other words, volts per amp is a measure of resistance in the circuit.
What is the relationship between capacitance and current in an electrical circuit?
The relationship between capacitance and current in an electrical circuit is that capacitance affects the flow of current in the circuit. A higher capacitance means the circuit can store more charge, which can impact the current flowing through the circuit. The current in a circuit with capacitance can change over time as the capacitor charges and discharges.
What is the relationship between power (P), current (i), and resistance (r) in an electrical circuit?
The relationship between power (P), current (i), and resistance (r) in an electrical circuit is described by the formula P i2 r. This means that power is directly proportional to the square of the current and the resistance in the circuit.
What is the relationship between phase angle and impedance in an electrical circuit?
In an electrical circuit, the phase angle represents the time delay between the voltage and current waveforms. The impedance of a circuit is the total opposition to the flow of current. The relationship between phase angle and impedance is that the phase angle is determined by the ratio of the reactance to the resistance in the circuit, which affects the overall impedance.
What is the relationship between wire self inductance and the efficiency of an electrical circuit?
The relationship between wire self inductance and the efficiency of an electrical circuit is that higher self inductance in the wire can lead to lower efficiency in the circuit. This is because self inductance can cause energy losses in the form of heat, reducing the overall efficiency of the circuit.
What is the relationship between resistance and current in an electrical circuit?
The relationship between resistance and current in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied and inversely proportional to the resistance in the circuit. In simpler terms, as resistance increases, the current flowing through the circuit decreases, and vice versa.
What is the relationship between voltage and frequency in an electrical circuit?
In an electrical circuit, the relationship between voltage and frequency is that they are independent of each other. Voltage refers to the electrical potential difference between two points in a circuit, measured in volts. Frequency, on the other hand, refers to the number of cycles per second of an alternating current, measured in hertz. While voltage can affect the power of an electrical circuit, frequency determines the speed at which the current alternates direction.
What is the relationship between current and resistance in an electrical circuit?
In an electrical circuit, the relationship between current and resistance is described by Ohm's Law. This law states that the current flowing through a circuit is directly proportional to the voltage applied and inversely proportional to the resistance in the circuit. In simpler terms, as resistance increases, the current flowing through the circuit decreases, and vice versa.
