Energy is measured in kWh, and 1 kWh equals one &#8220;unit&#8221;.<\/li>\n<li><strong>Soldering:<\/strong> Solder is a tin-lead alloy, commonly 60\/40. Flux cleans oxide and helps the solder flow. Use <strong>rosin flux<\/strong> for electrical work, and never acid flux because it corrodes the joint.<\/li>\n<li><strong>Dry (cold) joint:<\/strong> A dull, grainy joint caused by insufficient heat.

Example: 230 V across 46 \u03a9 gives 5 A.<\/li>\n<li><strong>Kirchhoff&#8217;s laws:<\/strong> KCL says the algebraic sum of currents at a junction is zero (conservation of charge). KVL says the algebraic sum of EMFs and voltage drops in a closed loop is zero (conservation of energy).<\/li>\n<li><strong>Temperature and resistance:<\/strong> Metals increase in resistance as they heat up. Semiconductors, carbon, insulators and electrolytes decrease. Eureka and manganin change very little.<\/li>\n<li><strong>Chemical effect:<\/strong> Electrolysis splits an electrolyte. The anode is connected to the positive terminal, the cathode to the negative. It is used in electroplating and refining. Faraday&#8217;s first law: m = Z I t.<\/li>\n<li><strong>Laws of resistance:<\/strong> R is proportional to length, inversely proportional to area, and depends on material and temperature. If a wire is stretched to double its length, its resistance becomes <strong>four times<\/strong>.<\/li>\n<li><strong>Cells:<\/strong> Primary cells (dry cell, Leclanch\u00e9) cannot be recharged. Secondary cells (lead-acid, Ni-Cd, Li-ion) can. A depolariser (MnO\u2082 in a dry cell) removes hydrogen bubbles.<\/li>\n<li><strong>Grouping:<\/strong> In series, EMF adds up (nE) and internal resistance is nr. In parallel, EMF stays E, internal resistance is r\/n, and current capacity increases.<\/li>\n<li><strong>Care of a lead-acid battery:<\/strong> Top up only with distilled water. Fully charged specific gravity is about 1.250\u20131.280, measured with a hydrometer. Keep the terminals clean and greased, and avoid overcharging.<\/li>\n<li><strong>Buckling:<\/strong> Plates bend because of excess current, short circuit or overheating.<\/li>\n<li><strong>Sedimentation:<\/strong> Active material shed from the plates collects at the bottom of the cell.
