Disadvantages of Solar Power in NZ
Intermittent energy source, high initial costs, space requirements, energy storage challenges
Conductors vs. Insulators
Conductors, like copper, allow electrons to move freely between atoms, enabling electricity to flow. Insulators, such as plastic, prevent electron movement, stopping the electrical flow. This difference makes copper ideal for wires and plastic idesuitableal for insulating wireexteriors.
Current is measured with an ammeter and is expressed in amps (A). Voltage is measured with a voltmeter and is expressed in volts (V). Current is the rate of electron flow, while voltage is the energy per charge.
Series vs. Parallel CircuitsIn series circuits, adding more bulbs increases resistance and decreases current, making bulbs dimmer. In parallel circuits, each bulb gets the full voltage, making them brighter. Parallel circuits are also more reliable since one broken bulb doesn’t affect others.
Solar Power in New ZealandSolar power is renewable and doesn’t contribute to climate change, but it only works during the day. Batteries are needed to store energy for nighttime use, impacting reliability and cost.
Series circuits
Simple, do not overheat easily, break if one component fails
Parallel circuits
Maintain constant voltage, allow components to be connected/disconnected without affecting others, require more wiring, cannot increase voltage
Correct Connection of MetersAmmeters should be connected in series to measure current correctly. Voltmeters should be connected in parallel to measure voltage accurately.
A balance of forces: The pressure inside an inflated balloon is greater than the pressure outside it. When air is blown inside the balloon, the molecules of air inside start bumping against the walls of the balloon, exerting a pressure force. Meanwhile, the air molecules outside the balloon also exert a pressure force on the balloon's surface. Since there are more air molecules inside the balloon than outside, the pressure force inside is greater than the pressure force outside.
egg drop parachute? Parachutes work based on air resistance, also known as drag. A falling object (egg) has a downward force acting on it due to gravity. When a parachute is deployed, it catches the air, creating a force that opposes the downward pull of gravity. This opposing force slows down the descent of the parachute and anything attached to it, such as an egg
